EWs_Si_lines.tar: Directory containing for various logg and microturbulence values, the EWs of the Si lines measured in the synthetic spectra as a function of Teff. lines_lists.tar: Directory containing for BO, B1 and B2 stars the list of lines I consider unblended for several elements. Also contains files with details about the strength of the various Si lines from A0 to O9. spectra_delta_cet.tar: Directory containing my own normalised spectra of delta Cet. syn_1938.tar and syn_2338.tar: Directories containing the NLTE DETAIL/SURFACE synthetic spectra for Teff=19000 and 23000 K (logg=3.8 cgs in both cases) syn_Balmer.tar: Directory containing synthetic spectra with the hydrogen lines for a given logg and Teff.
